  • Patent number: 9555150
    Abstract: An absorbent article, such as a diaper, panty diaper, sanitary napkin or incontinence device includes a topsheet, a backsheet and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an anti-bacterial agent or an alkali metal or alkaline earth metal chloride in combination with an organic zinc salt, in particular, zinc ricinoleate. The combination of antibacterial or (earth) alkali metal chloride and organic zinc salt exerts a synergetic effect in the suppression of malodours, such as ammonia.
